Hereinafter, the present invention will be described in detail with reference to examples, etc., but the present invention is not limited to the following examples, etc., and can be arbitrarily modified without departing from the scope of the present invention. In this specification, "~" is used as an expression including numerical values or physical quantities before and after it. Also, in this specification, the expression "A and/or B" includes "only A," "only B," and "both A and B."

The present invention relates to a skin care composition containing an acetic acid extract of onion bulbs.

As used herein, "skin beautifying composition" means a composition for maintaining or improving the condition of the user's skin and maintaining or enhancing the aesthetic appearance of the skin. Specific examples include amelioration of wrinkles, prevention and amelioration of skin aging, amelioration of firmness and texture of the skin, and provision of transparency. The skin care composition of the present invention exhibits a particularly excellent effect in improving wrinkles, as shown in Examples.

Hereinafter, the skin care composition of the present invention will be described in more detail.

The onion bulb acetic acid extract to be blended in the skin beauty composition of the present invention is an acetic acid extract of onion (scientific name: Allium cepa) bulbs (bulbs).
An onion is a perennial plant belonging to the genus Allium of the family Liliaceae, and its bulbs are widely used as food. Onion bulbs are traditionally considered to have medicinal effects such as diuretic and antibacterial effects, and are also said to have antioxidant, anti-aging and anti-allergic effects.

The type of onion used as a raw material is not particularly limited, and any of yellow onion, white onion and purple onion can be used.

In the present invention, the term "extract" is a general concept that refers to the onion bulbs to be extracted, or the onion bulbs to be extracted, or the onion bulbs that are finely chopped as necessary, and extracted with a solvent to increase the content of the active ingredient. is. Specifically, it includes an extract obtained by using onion bulbs as an extraction raw material, a diluted or concentrated solution of the extract, or a crude or purified product thereof. In addition, the dried product obtained by drying the extract is also considered as the extract.

As shown in the examples, the active ingredients contained in onion bulbs and contributing to skin beauty are acetic acid-soluble ingredients.
As an extraction solvent, acetic acid alone may be used, but hydrous acetic acid, which is a mixture of acetic acid and water, which is readily available, may also be used. Water that can be used as an extraction solvent includes purified water, ion-exchanged water, physiological saline, and the like.

In the case of hydrous acetic acid, the mixing ratio of acetic acid and water can be appropriately adjusted as long as the effect of the present invention (skin cosmetic effect such as wrinkle improvement) is not impaired, but usually the acetic acid concentration is 1 to 50% by weight. .
The hydrous acetic acid may be synthetic vinegar or brewed vinegar, but brewed vinegar is preferred. Synthetic vinegar and brewed vinegar can be used after being appropriately concentrated or diluted with water so as to have a predetermined acetic acid concentration.
Brewed vinegar is an edible acetic acid aqueous solution produced by acetic acid fermentation of commercially available grain vinegar (rice vinegar, brown rice vinegar, rice black vinegar, barley black vinegar, etc.) and fruit vinegar (apple vinegar, grape vinegar, etc.). is. Among these, rice vinegar and apple cider vinegar are suitable as the extraction solvent for the acetic acid extract of the onion bulb of the present invention, since they contain organic acids other than acetic acid and useful components such as polyphenols.
Commercially available rice vinegar and apple cider vinegar can be suitably used, and may be used alone or in combination. The mixing ratio (volume ratio) when mixing rice vinegar and apple cider vinegar is preferably rice vinegar:apple cider vinegar=10:90 to 90:10.

Moreover, the extraction solvent may contain a solvent other than acetic acid and water as long as the effects of the present invention are not impaired. Specific examples include lower alcohols having 1 to 5 carbon atoms such as water, ethanol, propyl alcohol and isopropyl alcohol; organic acids such as formic acid, butyric acid, oxalic acid, malic acid, lactic acid, tartaric acid, citric acid and succinic acid; , 3-butylene glycol, propylene glycol, and polyhydric alcohols having 2 to 5 carbon atoms such as glycerin. Moreover, the extraction solvent may contain an additive. Examples include viscosity modifiers.

The skin care composition of the present invention preferably contains baking soda together with the onion bulb acetic acid extract. Baking soda (sodium bicarbonate) is a sodium bicarbonate salt with the chemical formula NaHCO ₃ that is alkaline when dissolved in water.

As shown in the examples, wrinkle improvement, moisturizing effect, and skin beautifying effect (improvement of texture) are observed even with the onion bulb acetic acid extract alone. Effects (especially wrinkle improvement) are recognized. Although the details of how the combination of the acetic acid extract of onion bulbs and baking soda improves the skin beautifying effect are unknown, as shown in the Examples, the water beautifying effect of onion bulbs rather deteriorates. Therefore, it is presumed that there is a synergistic action between the acetic acid-soluble component contained in the onion bulb and baking soda.

The contents of the acetic acid extract of onion bulbs and baking soda in the skin care composition of the present invention may be appropriately contained within the range in which the effects thereof are exhibited. When a mixture of rice vinegar and apple cider vinegar is used as the extraction solvent, 0.1 to 1 g of sodium bicarbonate is used per 100 mL of the onion bulb extract.

<Other ingredients>
The skin care composition of the present invention may contain other ingredients in addition to the onion bulb acetic acid extract and baking soda as long as the objects of the present invention are not impaired. Other ingredients are not particularly limited as long as they are pharmaceutically or cosmetically acceptable ingredients.

For example, it may contain bisabolol, vitamin C or a vitamin C derivative, rice bran extract, and prune yeast decomposition extract as components that promote whitening effect.

In addition, it may contain Himefuuro extract, yeast polysaccharide, red wine yeast, chamomilla extract, etc., which are ingredients that promote skin turnover.

In addition, human ceramide, hyaluronic acid (sodium hyaluronate, acetylated hyaluronic acid, hydrolyzed hyaluronic acid, etc.) and the like may be contained as moisturizing ingredients.

<Form and method of use of skin beauty composition>
The form of the skin care composition of the present invention is not limited as long as it can be applied to human skin, and is appropriately determined according to the method of use. can be used in various forms. Among these, it is preferable to use it as a lotion because of its applicability to the skin including the face.

When the skin care composition of the present invention is used as a lotion (water-based liquid agent), the solvent is water (preferably purified water), and the ingredients used in conventionally known lotions are blended therein. good too. For example, ethanol, glycerin, antioxidants, whitening agents, ultraviolet absorbers, solubilizers, moisturizing agents, pigments, pH adjusters, emulsifiers, thickeners, fragrances, and other optional ingredients may impair the effects of the present invention. It can be contained in an arbitrary blending ratio within the range of no.

The skin care composition of the present invention may be produced by a generally known method depending on its form. For example, when the form is a lotion, it can be produced by mixing an onion bulb acetic acid extract, baking soda, and water (and other ingredients such as glycerin, if necessary) in the desired proportions.

The skin beautifying composition of the present invention is typically labeled as having a skin beautifying effect on any of the main body, packaging, instructions, and promotional materials (including web pages) of the product according to the present invention. use.

The skin care method of the present invention is characterized by including the step of applying the skin care composition of the present invention to the skin (excluding medical practice). Direct application or spray application may be performed depending on the form of the skin care composition of the present invention. Typically, a method of applying the skin cosmetic composition of the present invention to the skin of a subject can be mentioned as a treatment at an aesthetic salon or the like that does not perform medical procedures.

EXAMPLES The present invention will be described in more detail with reference to examples below, but the present invention is not limited to these.

<Experimental example 1>
After removing the epidermis from 2 yellow onions (approximately 600 g), the bulbs were sliced. Sliced onion bulbs were added to 450 mL of a mixed liquid of vinegar as an extraction solvent (a mixed liquid consisting of 225 mL of rice vinegar (trade name: Mizkan Junmai Vinegar) and 225 mL of apple cider vinegar (trade name: Mizkan Junmai Vinegar)). After soaking and standing at room temperature (about 20° C.) for 12 hours, the solid content was removed to obtain the onion bulb acetic acid extract (undiluted solution) of Experimental Example 1.

<Experimental example 2>
An acetic acid extract of onion bulbs was produced in the same manner as in Example 1, and 2 g of sodium bicarbonate was added to 400 mL of the acetic acid extract of onion bulbs obtained and stirred until completely dissolved to obtain the composition of Experimental Example 2. (undiluted solution) was obtained.

<Experimental Example 3> (Comparative Example)
By adding 2 g of sodium bicarbonate to 400 mL of water and stirring until completely dissolved, the composition (undiluted solution) of Experimental Example 3 was obtained.

<Experimental Example 4> (Comparative Example)
An aqueous extract of onion bulbs was obtained in the same manner as in Example 1, except that 400 mL of water was used as the extraction solvent instead of 400 mL of the vinegar mixture.
2 g of sodium bicarbonate was added to 400 mL of the resulting aqueous extract of onion bulbs, and the mixture was stirred until completely dissolved to obtain the composition (undiluted solution) of Experimental Example 4.

(adjustment of lotion)
40 mL of the composition (undiluted solution) of Experimental Examples 1 to 4 above, 50 mL of purified water, and 10 mL of glycerin were mixed to obtain lotions of Experimental Examples 1 to 4.

(monitor test)
8 monitors (2 people in their 20s (male and female), 2 people in their 30s (male and female), 1 person in their 50s (female), 2 people in their 60s (male and female), 1 person in their 70s (female)), Experimental example 1 ~ The lotion of No. 4 was applied to the face once a day for 5 weeks, and the condition of the skin after use was evaluated.
Table 1 shows the evaluation results after 3 weeks and 5 weeks. In addition, FIG. 1 (third week) and FIG. 2 (fifth week) show the summary of the questionnaire of the monitor test on which Table 1 is based, respectively.

Evaluation criteria are as follows.
<Wrinkle improvement>
2 points: Most effects were confirmed 1 point: Partial effects were confirmed 0 points: Effects were not confirmed -1 point: Wrinkles and sagging increased -2 points: Skin abnormalities <Moisturizing effect>
2 points: Confirmation of moist feeling 1 point: Confirmation of slightly moist feeling 0 points: No effect confirmed -1 point: Feeling of dryness and tightness -2 points: Skin abnormality, etc. <Beautiful skin effect (skin texture)>
2 points: Most effects were confirmed 1 point: Some effects were confirmed 0 points: Effects were not confirmed -1 point: Texture became rough -2 points: Skin abnormalities, etc.

As shown in Table 1, in Experimental Examples 1 and 2 containing the onion bulb acetic acid extract, wrinkle improvement, moisturizing effect, and skin beautifying effect were all observed. Experimental Example 2 (onion bulb acetic acid extract and baking soda) was found to be superior to Example 1 (onion bulb acetic acid extract only) in wrinkle improvement, moisturizing effect, and skin beautifying effect from the 3rd week ( Especially wrinkle improvement). On the other hand, in Experimental Example 3 (aqueous sodium bicarbonate solution), which is a comparative example, neither wrinkle improvement, moisturizing effect, nor skin beautifying effect was observed. In addition, in Experimental Example 4 (onion bulb water extract and baking soda) in which acetic acid was not used as an extraction solvent, no wrinkle improvement, moisturizing effect, or skin beautifying effect was observed, and skin abnormalities occurred at the 3rd week. Due to multiple monitors, the evaluation was discontinued at that point.

From the above results, even with only the onion bulb acetic acid extract of Experimental Example 1, wrinkle improvement, moisturizing effect, and skin beautifying effect (improvement of texture) are observed. It was found that a more excellent skin cosmetic effect (especially wrinkle improvement) was recognized in a shorter period of time. In addition, as in Experimental Example 4, the aqueous extract of onion bulbs (and baking soda) rather reduces the skin-beautifying effect and adversely affects the skin. It is considered that the action is generated and a more excellent skin cosmetic effect is exhibited.
